There's also a paperback book that goes with this that I forgot to add to the set that I'm throwing in. Considering that a large PO flat rate box would fit (It's also usually more expensive than going by weight-so I hardly ever do that.) is $12.95, it wouldn't cost more than that. If by some odd stroke of misfortune, the box weighs more than $12.95 worth-I will send it in a flat rate large box-so, it would never cost more than $12.95, but it should be less. Is that too confusing? I do get wordy.
